The Earth for All: Two Possible Scenarios

The authors took advantage of a newly developed dynamics model to explore two distinct possible scenarios that could play out over the course of this century. The first scenario, called Too Little Too Late, entails the planet continuing to develop economically in the same way it has for the past 50 years. This version of events would also lead to the end of extreme poverty in a generation by 2060 along with a market impact on global population trends. Meanwhile, the second potential scenario is called the giant leap. According to this possible sequence of events, the world population will peak at roughly 8.5 billion by the year 2040 before dropping off to 6 billion by the end of the century.
